Abstract
The utility model discloses a wear-resistant nozzle for a spray gun of a roasting furnace. The nozzle comprises a nozzle body and a nozzle core, wherein the nozzle body is fixed outside the nozzle core; the nozzle core is a rotating nozzle core; a protection layer is arranged on the inner wall of the nozzle core; and the nozzle core rotates and sprays in the range of 30 to 150 degrees in a reciprocating mode. The nozzle has a simple structure and is low in cost, convenient to use and high in wear resistance and corrosion resistance, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of acid regeneration equipment part, particularly relates to a kind of wear resistant spray nozzle for spray gun of roasting furnace.
Background technology
Spray roasting acid regeneration device is reasonable spent acid treatment process in industrial scale.Nozzle of spray gun for roasting furnace is indispensable equipment in the acid regeneration technological process, spent acid atomizing spray after being mainly used in roaster, will filtering via concentrating waste acid filter, make spent acid after roasting, isolate its inner brown iron oxide, the quality of nozzle has directly determined the quality of brown iron oxide, and the nozzle that uses at present, complex structure damages easily, and cost is high.
For example the patent No. is CN201020186665.3, and publication number is the Chinese patent " nozzle of spray gun for roasting furnace " of CN201729882U.Disclose a kind of nozzle of spray gun for roasting furnace, it is characterized in that, comprised nozzle body and nozzle core, described nozzle body is set in the outside of nozzle core, and described nozzle core is the rotation spray core of being made by metal, has the jet angle of 120 degree.The weak point of this patent is that nozzle core causes nozzle short service life owing to being worn for a long time and corroding.
The utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, proposes a kind of wear resistant spray nozzle of spray gun of roasting furnace.The utility model adopts the inwall at nozzle core that protective layer is set, and has overcome prior art and has existed nozzle core owing to being worn for a long time and corroding, and causes nozzle short technical problem in service life; cost is low, and is simple in structure, easy to use; abrasion resistant corrosion resistant is good, has prolonged service life.
The utility model is realized by the following technical solutions:
A kind of wear resistant spray nozzle of spray gun of roasting furnace; comprise nozzle body and nozzle core, described nozzle body is fixed on the outside of nozzle core, and described nozzle core is the rotation spray core; it is characterized in that: the inwall of described nozzle core is provided with protective layer, and described nozzle core reciprocating rotary between 30 degree-150 degree sprays.
Described protective layer is the corundum ceramic layer, and the corundum ceramic layer is to form at high temperature more than 2300 ℃.
The connected mode of described nozzle body and nozzle core is the male and female snapping.
The connected mode of described nozzle body and nozzle core is for being threaded.
The utility model compared with prior art, its advantage is:
1, the utility model adopts the inwall at nozzle core that protective layer is set, and has overcome prior art and has existed nozzle core owing to being worn for a long time and corroding, and causes nozzle short technical problem in service life; cost is low, and is simple in structure, easy to use; abrasion resistant corrosion resistant is good, has prolonged service life.
2, to adopt protective layer be the corundum ceramic layer to the utility model, and the corundum ceramic layer is to form at high temperature more than 2300 ℃, and the corundum ceramic layer that forms at high temperature more than 2300 ℃ is as wear-resistant protective layer, and aluminium oxide hardness height, chemical inertness, high strength and plasticity are good.
3, the connected mode of the utility model employing nozzle body and nozzle core is the male and female snapping; Or the connected mode of nozzle body and nozzle core is for being threaded; Simple in structure, change, clean and safeguard very convenient.
